I am wondering if there are coins that are independent to the Bitcoin price? Like, if Bitcoin's value increases, the altcoin will not increase at the same time Bitcoin does. Or maybe, I am wrong that the price of Bitcoin doesn't have any effect to the value of altcoins? Please enlighten me with this topic. If there's any coins that are independent, what are the benefits that you can get in investing to that altcoin that you can't get in investing in Bitcoin?
Yes the prices of Altcoins tend to follow Bitcoin. This is mostly due to Altcoin/Bitcoin pairing being traded. Every major exchange offers BTC trading pairs. Because BTC is the top coin being traded for other alts in terms of market cap, volume, and general popularity, it is thus at the center of the crypto economy and has some gravity behind it. Therefore, the prices of Altcoins mostly follow Bitcoin’s prices.
